Hitachi Construction Machinery has begun operation of the Salt Lake City Parts Warehouse, in Utah, USA, to strengthen its supply system for service parts in western North America.

This new 173,000 sq.ft (16,072 sq.m) warehouse will enable the company to supply service parts, which were previously shipped from parts warehouses outside of Atlanta, more rapidly to dealers and customers in western North America.

Service parts for construction and mining machinery must be supplied to customers in a rapid and reliable manner to maintain stable machinery operation, the company states. The Hitachi Construction Machinery Group began operation of the Jackson Parts Warehouse (Jackson, Georgia) and McDonough Parts Warehouse (McDonough, Georgia) outside of Atlanta in 2022 to strengthen its parts supply system in the Americas. Previously, these warehouses supplied parts to regions all over the Americas including Canada, Central and South America.

The operation of the Salt Lake City Parts Warehouse is expected to shorten the delivery lead time by approximately one to three days for service parts shipped to dealers in the US states of Utah and Alaska, the Canadian province of Alberta, and other regions within western North America. The new warehouse is scheduled to store 30,000 different parts upon opening and ship around 500 orders per day.

Jeremy Dieterle, Vice President, Parts Hitachi Construction Machinery Americas, said: “When we were deciding upon the location for this warehouse it was important for us to be close to our customers. While this requires additional investment and complexity for us, our goal is to improve the speed of delivery to our customers, maintain world class fill rates and be a highly reliable partner.”

Hitachi Construction Machinery Americas says it is committed to its customers and dealer network with $140 million in parts inventory spread across its warehouses in the Americas to ensure high parts availability.

Going forward, the company plans to expand warehouse operations through further enhancement of equipment and systems. Furthermore, operation of the warehouse will be entrusted to LOGISTEED America, Inc under a third-party logistics arrangement similar to the parts warehouses outside of Atlanta.

Rio Tinto is progressing its mobile equipment electrification move at the Kennecott underground operation near Salt Lake City, Utah, having transitioned from using Sandvik Mining & Rock Solutions battery-electric loaders and trucks in a proof of concept to commercially deploying Sandvik battery-electric TH550B trucks and a Sandvik LH518iB loader.

Just last year, Rio Tinto approved $498 million of funding to deliver underground development and infrastructure for an area known as the North Rim Skarn (NRS). Production from the NRS is due to commence this year and is expected to ramp up over two years, to deliver around 70,000 tonnes of additional mined copper over the next 10 years alongside open-pit operations at Kennecott.

This followed a September 2022 announcement where Rio Tinto approved development capital totalling $55 million to start underground mining in an area known as the Lower Commercial Skarn (LCS) at Kennecott. Underground mining within LCS started in February 2023 and is expected to deliver a total of around 30,000 tonnes of additional mined copper through the period to 2028.

These two investments will support Kennecott in building a world-class underground mine which will leverage battery-electric vehicle (BEV) technology, following a trial with Sandvik equipment in 2022 involving an LH518B loader and Z50 truck.

The first LH518iB loader in North America has just been delivered to site, with the automation-capable vehicle equipped with Sandvik’s patented self-swapping battery system, including the AutoSwap and AutoConnect functions, to minimise infrastructure needs and enable the loader to return to operation significantly sooner than ‘fast-charge’ mining BEVs, Sandvik claims.

Since launching the vehicle in March 2023, Sandvik has confirmed orders or made deliveries of the LH518iB to operations owned by LKAB, Boliden,Torex Gold, Foran Mining, Rana Gruber and Byrnecut.

Rio Tinto will complement these machines with a fleet of Sandvik TH550Bs, some of which are already operating on site. This 50-t payload truck combine Sandvik’s 50 years of experience in developing loaders and trucks with Artisan™’s innovative electric drivelines and battery packs. The electric drivetrain delivers 560 kW of power and 6,000 Nm of total torque output, allowing for higher ramp speeds for shorter cycle times and an efficient ore moving process, according to the OEM. All of this comes with zero emissions.

They also come with AutoSwap and AutoConnect functions that Sandvik has refined for battery swap processes that take only a few minutes.

Rio Tinto has previously stated on battery-electric vehicle use: “BEVs create a safer and healthier workplace for employees underground, increase the productivity of the mine and reduce emissions from operations.”

Rio Tinto completes 5 MW solar power plant build at Kennecott

Base metals, Environmental, Mine operation news, Power supply for mines, Sustainable mining, , , , , , ,

Rio Tinto has completed construction on a new 5 MW solar power plant at its Kennecott copper operation in Utah, USA, with commissioning expected in the coming weeks.

The 12,800 solar panel power plant will enable Kennecott to reduce its operational emissions by 3,000 t/y of carbon dioxide equivalent, Rio Tinto says. It will also serve as a pilot project with the goal of expanding Kennecott’s solar energy supply in the future.

Shifting to sustainable energy solutions is a priority for Kennecott, the company says. The mine closed down its coal-fired power plant in 2019, moving to electricity paired with renewable energy certificates. This resulted in a 65% reduction in its carbon footprint and the elimination of over 1 Mt/y of carbon dioxide output.

Rio Tinto Kennecott Managing Director, Nate Foster, said: “Rio Tinto Kennecott has a key role to play in supporting the energy transition. We supply US companies with the copper and tellurium they need to produce solar panels, wind turbines, and conductors. We also continue to take steps to further decarbonise our business, from our battery-electric vehicle trial to our renewable diesel trial and now to our very own solar plant.”

The location of the 30-acre (12.1-ha) solar array was carefully selected to minimise visual and environmental impacts, Rio Tinto says. It is adjacent to other existing industrial operations, away from residential and commercial zones, with earthen berms from the railway providing a visual barrier to most of the installation.

Last year, Rio Tinto started producing tellurium as a by-product of mining and refining copper at Kennecott, becoming one of only two US producers of this critical mineral. Both copper and tellurium are vital components of photovoltaic solar panels. The tellurium from Kennecott is refined by 5N Plus, a producer of specialty semiconductors and performance materials, before being supplied primarily to First Solar for use in its solar panels.

Rio Tinto aims to reduce its global Scope 1 and 2 emissions by 50% by 2030 and to achieve net zero emissions by 2050.

Fortune Minerals, Rio Tinto join forces to improve cobalt and bismuth recoveries

Base metals, Energy minerals, Metallurgy, , , , , , , , , , ,

Fortune Minerals and Rio Tinto have agreed on a collaboration to develop technology that will improve recovery of the critical minerals cobalt and bismuth.

Under a Memorandum of Understanding (MoU) signed between the companies, testing will be done at Rio Tinto Kennecott’s integrated copper mining and smelting operations in Utah and at Fortune’s planned Alberta Refinery.

The partnership aims to maximise the value of critical mineral supply chain investments and increase Fortune’s planned cobalt and bismuth refining operations to process co-product streams of the minerals recovered from the Kennecott smelter, Fortune said.

In 2020, the Canadian and U.S. governments signed a Joint Action Plan on Critical Mineral Collaboration to enable more North American production of the critical minerals needed in new technologies. Cobalt and bismuth are both included in this list and are used for sustainable energy resources. Fortune and Rio Tinto are pleased to establish this partnership and work together to expand North American supply chains, they said.

Robin Goad, President and CEO of Fortune Minerals, said: “Working with Rio Tinto to recover metals from their co-product streams is part of our corporate strategy to expand production of critical minerals, and we are excited to be working with one of the world’s premier mining companies on the first of these opportunities. This collaboration could provide a solution to support greater production of the metals needed for the energy transition and growing sustainable economy.”

Rio Tinto Kennecott Managing Director, Nate Foster, commented: “We are committed to find better ways to provide the materials the world needs to grow and decarbonise. We are enthusiastic about this partnership with Fortune Minerals as we continue looking at our waste streams to develop new, sustainable sources of critical minerals here in North America.”

For 120 years, Kennecott, in Utah, has been mining and processing copper and other minerals including gold, silver, molybdenum and tellurium from the rich ore body of the Bingham Canyon mine (pictured).

Fortune is developing its 100%-owned, vertically integrated NICO cobalt-gold-bismuth-copper project in Canada. This asset is comprised of a planned mine, mill and concentrator in the Northwest Territories and a related hydrometallurgical refinery in Alberta where concentrates from the mine would be processed.

Fortune and Rio Tinto are working together to assess different process methods and technology options to recover the bismuth and cobalt contained in Kennecott’s smelter waste streams. This includes assessing the effectiveness of blending Rio Tinto’s intermediate products with NICO project concentrates and conducting batch recovery tests using Fortune’s refinery flow sheets.

The Bingham Canyon copper mine in Utah, USA, has selected the Cat® MineStar™ Fleet management system as part of its plans to optimise open pit operations at the mine, owned by Rio Tinto, Caterpillar says.

Caterpillar Inc and Wheeler Machinery recently completed installation of a Cat MineStar Fleet management system at the mine, which, rather than upgrading the mine’s previous fleet management system, chose to deploy MineStar Fleet. This switch has, Caterpillar says, optimised the mine site’s equipment tracking, production recording, material management and truck assignment, and it has further expanded the technology relationship between Caterpillar and Rio Tinto.

Ryan Howell, Mining Technology Commercial Product Manager at Caterpillar, said: “For 15 years, Rio Tinto has used MineStar Terrain and has expanded its MineStar capabilities in recent years at locations like Gudai Darri and Marandoo, autonomous mine sites in Western Australia. Bingham Canyon Mine is the first MineStar Fleet site in Rio Tinto history, and this extends the company’s application of MineStar capabilities. Our team is proud of this MineStar Fleet system installation. We are honoured to be there to support the mine site’s fleet management needs.”

Joshua Wood, Principal Advisor, Surface Mining Centre of Excellence at Rio Tinto, added: “The close collaboration between the Rio Tinto Group team, Caterpillar, dealer and Kennecott ensured a successful deployment at Kennecott and their desire to be the flagship for future MineStar sites.”

Even though it wasn’t the easiest route for the mine, the cost-benefit analysis showed significant benefits long term using MineStar Fleet, including seamless integration with MineStar Terrain currently used by the mine, Caterpillar said.

Mike Gray, General Manager for Wheeler Machinery, said: “A true partnership with the supplier, dealer and customer allows for large-scale technology projects like this to be completed successfully with minimal impact to production.”

An incremental approach was devised to minimise the system installation loss-time impact on mining operations for bringing nearly 100 trucks, plus more than 40 supporting dozers, shovels and drills, online with MineStar Fleet. Caterpillar and Wheeler worked together to provide a quick turn-around time with best-in-class implementation, Caterpillar said.

Bryce Olson, Mine Monitoring and Control Superintendent at the Kennecott Bingham Canyon Mine, said: “We have been impressed with the partnership, and we share the same vision and have the correct team to get us there. We flipped the switch, and we haven’t gone backwards. We immediately started using MineStar Fleet’s open assignment, load-haul-dump and auto fuel advanced features.”

Cat MineStar Fleet automatically records and tracks data up and down a mine’s value chain, providing insights that help miners identify what is working and fix what is not to meet production targets, Caterpillar says. Fleet allows miners to view the entire operation at a glance on a computer and gain insights into key cost drivers – such as fuel, tyres, service parts and idle time – and improve haul fleet production and shovel utilisation.

Rio Tinto has approved a $55 million investment in development capital to start underground mining and expand production at its Kennecott copper operations in Utah, USA.

Underground mining will initially focus on an area known as the Lower Commercial Skarn (LCS), which will deliver a total of around 30,000 t of additional high-quality mined copper through the period to 2027 alongside open-pit operations, Rio says. The first ore is expected to be produced in early 2023, with full production in the second half of the year. It will be processed through the existing facilities at Kennecott, one of only two operating copper smelters in the US.

Kennecott holds the potential for significant and attractive underground development. The LCS is the first step towards this, with a mineral resource of 7.5 Mt at 1.9% Cu, 0.84 g/t Au, 11.26 g/t Ag and 0.015% Mo identified based on drilling and a probable reserve of 1.7 Mt at 1.9% Cu, 0.71 g/t Au, 10.07 g/t Ag and 0.044% Mo.

Underground battery-electric vehicles are currently being trialled at Kennecott to improve employee health and safety, increase productivity and reduce carbon emissions from future underground mining fleets. A battery-electric haul truck and loader supplied by Sandvik Mining and Rock Solutions – a Sandvik LH518B 18 t battery-electric LHD and a Sandvik Z50 50 t battery-electric haul truck – are being used to evaluate performance and suitability as part of underground development work.

Rio Tinto Copper Chief Executive, Bold Baatar, said: “This investment will allow us to quickly bring additional volumes of high-quality copper to the market and build our knowledge and capabilities as we evaluate larger scale underground mining at Kennecott. We are progressing a range of options for a significant resource that is yet to be developed at Kennecott, which could extend our supply of copper and other critical materials needed for electric vehicles and renewable power technologies.

“Trialling underground battery-electric vehicles is an exciting step in our work to create a safer workplace for our employees, increase the productivity of the mine and reduce emissions from our operations. We look forward to seeing their potential for deployment.”

Existing undergound infrastructure is currently being extended to enable early access to the next underground resource and undertake characterisation studies. A feasibility study to inform decisions on the next phase of underground production is expected to be completed in 2023. This will be one of several potential stages currently being investigated.

Feasibility studies are also being progressed to extend open-pit mining at Kennecott beyond 2032.

Rio Tinto produces first tellurium from Kennecott copper operation

Base metals, Energy minerals, Mine operation news, Mineral processing, Sustainable mining, , , , , ,

Rio Tinto has started producing tellurium at its Kennecott copper operation in Utah, becoming one of only two US producers of the critical mineral used in advanced thin film photovoltaic solar panels.

The tellurium will be refined in North America by 5N Plus, a global producer of specialty semiconductors and performance materials, under a commercial agreement between 5N Plus and Rio Tinto. The refined tellurium will primarily be supplied to First Solar, the only U-based company among the world’s 10 largest solar manufacturers, under an existing supply contract between 5N Plus and First Solar. 5N Plus will also use the tellurium to manufacture ultra-high purity semiconductor materials at its facility in St. George, Utah, to serve the security and medical imaging markets.

Approximately 20 tons (18 t) of tellurium will be produced per year through a new $2.9 million circuit built at the Kennecott refinery. This valuable material is recovered from by-product streams generated during the copper refining process, reducing the amount of waste that needs to be treated and discarded as mine tailings.

Tellurium is listed as a critical mineral by the US Government due to its importance to the economy and energy security.

Rio Tinto Copper Chief Operating Officer, Clayton Walker, said: “We are proud to deliver a new domestic supply of tellurium to support the manufacturing of solar panels and other critical equipment here in the United States. Approximately 90% of the world’s tellurium resource is contained in copper ore and no other metal has more critical mineral by-products than copper. The Kennecott team is constantly looking for ways to extract new critical minerals to meet emerging demand for the clean energy transition.”

5N Plus President and Chief Executive Officer, Gervais Jacques, said: “As a leading global supplier of specialty semiconductor compounds for applications in renewable energy, security and medical imaging, 5N Plus is proud of this partnership with Rio Tinto, and to further leverage its expertise in the transformation of mining and metallurgical by-products into high purity value-added critical minerals such as tellurium, here in North America.”

First Solar Chief Manufacturing Operations Officer, Mike Koralewski, added: “Rio Tinto’s decision to invest in tellurium is a win for responsibly-produced, American solar. We’re thrilled that tellurium from Kennecott will play a role in powering our country’s transition to a sustainable energy future.”

Tellurium is one of 10 metals and products recovered from ore extracted at Kennecott, which produces nearly 15% of US copper with the country’s lowest carbon footprint, Rio Tinto says.

Murray & Roberts’ Cementation Americas business wins Rio and BHP contracts

Base metals, Energy minerals, Mine operation news, Mine shafts and equipment, Mining services, , , , , , , , ,

Murray & Roberts’ Cementation Americas business has confirmed two new mining contracts with Rio Tinto and BHP.

Cementation USA secured the Underground Characterisation Development and Infrastructure project in Utah for Rio Tinto’s Kennecott copper operations (open pit, pictured). The value of this agreement is circa-$70 million, with the initial scope including lateral development and associated infrastructure works.

Rio, only last month, approved a $108 million investment in underground development to enable early orebody access and undertake orebody characterisation studies for underground mining at the Kennecott copper operations.

The contract award positions Cementation USA well for the potential significant scope growth on this project, Murray & Roberts said.

Cementation Canada Inc has secured the completion of Phase 1 of the Jansen potash project in the province of Saskatchewan for BHP. This scope includes the post liner excavation, steel and equipping of the shaft.

The value of the complete project award, subject to a sanction decision for the project, is around $170 million. Cementation Canada has, in the interim, received a works order to proceed with the first work package to the value of $12 million.

BHP said last month that it expected to make a decision on whether to move forward with Jansen, which is expected to produce 4.4 Mt/y of potash in its first phase, in the next two months.

Cementation Canada will apply to also deliver the following phases of the Jansen project, Murray & Roberts noted.

Murray & Roberts said: “During the past year, mining companies in the Americas have experienced prolonged COVID-19 impact, creating short-term order book pressure for engineering and contracting companies. These awards are evidence of new mining investments returning to the region.

“The forecast improvement in capital investment in the mining industry is encouraging and, considering the platform’s leading global position and growing near term project pipeline, there is good potential for accelerated growth for the group’s mining platform.”
